CHEM 2211 1nd Edition Lecture 29Outline of Last Lecture I. Sn1 reactions Outline of Current LectureI. Benzyl and allylic halide reactions Current LectureBenzyl and allylic halide reactions Benzyl and allylic halides undergo both Sn1 and Sn2 reactions Only Sn1 reactions: - Tert- benzyl halides- Tert-allylic halides Only Sn2 reactions: - n/a Both depending on outside factors - primary allylic halides - secondary allylic halides- primary benzyl halides - secondary benzyl halides Type of nucleophile - a good nucleophile (or higher nucleophilic concentration) o Sn2 reactions These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Poor nucleophile ( or low nucleophilic concentration) o Sn1 reactions Type of solvent - Polar solvents in liquid, solid or aqueous phase o Sn1 reaction The high the polarity the high rate of reaction - Nonpolar solvent o Sn2 reaction Increasing polarity of solvent will decrease rate of
